As a catastrophic inferno tore through a cultural treasure, US President Donald Trump assessed the response from 6440km away and offered unsolicited advice for firefighters trying to save Paris' Notre Dame Cathedral.
"Perhaps flying water tankers could be used to put it out," Trump tweeted from Air Force One, minutes before landing in Minnesota for a Tax Day speech. "Must act quickly!"
Trump's armchair observations were striking, even for a president who seems to offer an opinion about just about everything.
Just hours before, Trump had weighed in on Boeing's ongoing troubles after two crashes of its new airliner, suggesting a rebranding campaign is in order for the beleaguered 737 Max, and he'd spent the previous day commentating on professional golf as Tiger Woods overcame long odds to win the Masters.
"They're having a terrible, terrible fire," Trump said during his remarks in Minnesota, describing watching the flames on television from the presidential aircraft.
